Operation Manual – System Maintaining and Debugging
H3C S9500 Series Routing Switches
Note:
The debugging commands are usually used by administrators in diagnosing
network failure.
Output of the debugging information may reduce system efficiency, especially
during execution of the debugging all command.
After completing the debugging, you are recommended to use the undo debugging
all command to disable all the debugging functions.
You must configure the debugging, terminal debugging and terminal monitor
commands first to display the detailed debugging information on the terminal. For
the detailed description on the terminal debugging and terminal monitor
commands, refer to Information Center Commands in the System Volume.

1.3 System Maintaining Example

I. Network requirements
The IP address of the destination device is 10.1.1.4.
Display the routing devices a packet traverses from the current device to the
destination device.
II. Network diagram (omitted here)
III. Configuration procedure
<Sysname> tracert nis.nsf.net
traceroute to nis.nsf.net (10.1.1.4) 30 hops max, 40 bytes packet
1 128.3.112.1
2 128.32.216.1
3 128.32.136.23
4 128.32.168.22
5 128.32.197.4
6 131.119.2.5
7 129.140.70.13
8 129.140.71.6
9 129.140.81.7
10 10.1.1.4
The above output shows that a packet traverses nine routing devices from the source to
the destination device.
